Grizz Technographics vs TechnologyChecker

Grizz Technographics identifies software used by construction companies, including ERP, HR, and project management tools, for sales and marketing teams seeking accounts by technology profile. It tracks more than 100 construction technologies and lists over one million technology signals. Categories include accounting, payroll, estimating, and field tools as well as ERP and project management. Records receive A, B, or C confidence grades reflecting signal strength and corroboration. Grizz says it analyzes construction job postings daily and refreshes signals weekly; historical timelines show when companies changed software. Users can inspect a company's technology stack, find businesses using a competitor's product, and identify companies evaluating or implementing software. Data can be exported to CRM records by CSV or API, including HubSpot and Salesforce. The free tier offers sample data and limited company and technology details. Premium offers deeper data and a white-glove partnership, with pricing by discussion. The API is in early access, and its endpoints and response shapes may change.
